I miss my husband 😭

Our baby is 6 weeks old now and I am a stay at home mom. My husband works for the family business full time but when I was pregnant he was home often. After our boy turned 3 weeks old my husband when back to work and it's like he's gone 7am-8pm. I feel so alone and overwhelmed. My husband has been my best friend for 3 years and I'm really struggling since I don't get to share my day with him anymore plus I feel like I can't ask him for help because he works so hard all day already and he works 7 days a week. 💔💔💔 I am behind on housework, I can barely get a load of laundry done. I just want to cry.
